BACKGROUND

The Public Switched Telephone Network (PSTN) provides plain oldtelephone phone service (POTS) to the residential customer over atwisted cable pair. The Federal Communication Commission (FCC) createdregulations to identify and define ownership of the equipment andfacilities for POTS services. The Demarcation point was established asthe physical dividing line or boundary of POTS ownership between thePSTN and the customer. This Demarcation point establishes the phoneservice handoff and the associated responsibilities of performance,installation, and maintenance for the PSTN and the customer. ADemarcation point for POTS is typically represented by the PSTN orservice provider's grey color network interface Device (NID) installedon the exterior side of a residential house. The customer installs theirwire cable into the service providers RJ11 modular connector, which theRJ11 modular connector is located inside the NID. The Demarcation lineis the RJ11 module connector.

Other types of a Demarcation point or line is the outside service plant(OSP) cabinets, which these OSP cabinets are centrally located toprovide communication service to a serving area. In this application,the Demarcation point is a specified secured location inside the OSPcabinet where the customer only has access. This secured location mayhouse a telephone wiring punch-down block (Type 66), a wire cable patchpanel, or a fiber optic cable patch panel as the Demarcation point.

By way of further background, small form factor pluggable (SFP) Devicesare used to provide a flexible means of providing communication servicesfor the telecommunication network. The SFP Devices are typicallydeployed on communication network equipment such as an Ethernet accessswitch, Ethernet router, a broadband fiber multiplexer, or mediaconverters. SFP Devices are designed to support optical and wiredEthernet, TDM SONET, Fiber Channel, and other communications standards.As disclosed in my U.S. Pat. No. 10,446,909, SFP Devices can alsosupport a wireless interface, which wireless SFP (WSFP) Device cansupport IEEE802.11 (Wi-Fi), Bluetooth, LTE, 4G, 5G, and other wirelesstechnologies. Due to its small and portable physical size, SFP Deviceshave expanded in specifications to address other applications. SFPDevices presently are defined for SFP, SFP+, QSFP, QSFP+, QSPF28,QSFP-DD and OSPF technologies. SFP Devices are standardized amongequipment vendors and network operators to support interoperability. Dueto the low cost, size, and interoperability, SFP Devices are usedextensively in all communication service applications.

The telecommunication service and network have significantly evolvedbeyond the phone service. Telecommunication service provides voice,data, and video using wire cable, coax cable, fiber optic cables, andwireless service as a transport medium. The Demarcation point applies toall communication services, voice, data, video or any combinationthereof. The Demarcation point location determination may also besubject to a minimum point of entry (MPOE). MPOE is the most practicallocation to establish a Demarcation point at the serving facility. Theinformation infrastructure spans in size and complexity from a simplevoice call to a myriad of complex and dynamic information flow for homeautomation, video streaming, ecommerce and cloud computing. In everyinformation flow, there are boundaries which define privacy, ownership,and responsibilities between the communicating recipients. Theseboundaries are now virtual, logical, or physical and can be locatedanywhere.

Presently, there is a need to establish a Demarcation point for theseboundaries. Concurrently, there is a need to allow communicationsservices to be monitored and/or tested to ensure the services are highin quality and reliable. The methods, systems, Devices and Circuitrydisclosed herein fulfill these and other such needs.

One example of a prior art Demarcation Device is illustrated in thediagram of FIG. 1 (prior art), which depicts use of a “UniversalDemarcation Point” Device for providing multiple services forresidential customers. This Device provides audio, data, and videoservices through dedicated interfaces RJ type modular and coax. Thishybrid cable is comprised of a combination of wire, power, and opticalcables.

There are a number of disadvantages to a universal Demarcation typeDevice as shown in FIG. 1 (prior art). First, this prior art Deviceprovides a Demarcation point with dedicated services audio, data, andvideo services. If new services are added or changed after installation,the prior art Device must be powered off, disassembled, and updated forthe new service. This service update may require the prior art Device tobe updated at a service location or replaced with a new updated priorart Device. In either situation, the service is disrupted for an extendtime. Second, this prior art Device does not provide an off-the-shelfservice interface for any service or connector updates, replacements, orrepairs. Third, this prior art Device test functionality involvesdisengaging the service by removing the plug or coax from the prior artDevice connector for service isolation. The customer must then connect atest Device into the modular or coax connector to test their side of theDemarcation point. This prior art Device does not provide a Demarcationpoint with removable SFP type Devices or a Demarcation point with adifferential signal Port interface.

Thisprior art Device connects via a high speed connector to two wirelessrouters to establish a Demarcation point between two wireless serviceproviders. The prior art Device connects to an aggregation switch totransport the wireless service to another switch which distributes thewireless service among many Devices.

FIG. 18 illustrates a diagram of still another embodiment of thecommunications system and equipment of the present disclosure of aDemarcation established by the First Network 20. The Demarcation Device100 of this embodiment establishes a Demarcation point or line 10between a First Network 20 and a Second Network 30, specifically througha wireless SFP (WSFP) Device 116 a. The Device 100 allows communicationservice to be transported between First and Second Networks and for thecommunication service to be monitored and/or injected by any physicalmedia type. The Device 100 also allows the wireless signal to beextended using two WSFP devices with the same wireless signal interfaceor WSFP device type. An example is a WSFP Device 106 a and a WSFP Device116 a supporting IEEE 802.11 (Wi-Fi) standard or a WSFP Device 106 asupporting IEEE 802.11 (Wi-Fi), IEEE 802.15 (Bluetooth), 5G and a WSFPDevice 116 a supporting only IEEE 802.11 (Wi-Fi). Although both WSFPdevices conform to the same wireless signal interface the WSFP devicesmay be provisioned to have different wireless signal formats or options.As an example, the IEEE 802.11 standard defines operation for wirelessnetworks in both the 2.4 GHz and 5 GHz frequency ranges. The 2.4 GHzband is defined into 11 channels (1-11) and the 5 GHz hand can have 36to 165 channels. Adjacent Channel Interference (ACI) and Co-ChannelInterference (CCI) will result in Wi-Fi signal disruption andperformance degradation when 2.4 GHz or 5 GHz channels overlap andconflict. A static channel plan or a vendor's dynamic channelassessment/assignment algorithm, a WSFP device with a IEEE802.11 (Wi-Fi)signal interface with a static or vendor's channel plan may require oneor both WSFP devices to be provisioned for different channels or otherend-user requirements.
